The WEA14HPS45 is a complete high performance, low noise, 24 bits Fractional-N microwave synthesizer able to synthesize frequencies from 8 GHz to 14 GHz with the integrated VCOs. It consists of a low noise phase detector with lock detect indication, a programmable charge pump, a programmable bandwidth loop filter, a multi modulus Prescaler, and a 100+ band VCOs with autocalibration circuitry. Implemented in the GlobalFoundries 45RFSOI process, the WEA14HPS45 occupies a silicon area of 1.87mm2. It exhibits high performance, high integration and flexibility targeting 5G, Backhaul, SatCom and WLAN applications.
